Erratum to: Exploring the landscape of (anti-) de Sitter and Minkowski solutions: group manifolds, stability and scale separation
David Andriot, Ludwig Horer, Paul Marconnet
Abstract
With this erratum we aim at clarifying a confusion in our statements due to an abuse of language: while we often used the words "flat direction", what we meant was actually a "massless scalar field". The former refers to a scalar field which is completely absent of a scalar potential V , and which is for this reason massless. The latter is more general, allowing in particular scalar fields appearing in the scalar potential V , but which are massless either because of a specific functional dependence in V or because of the peculiarities of the solution where the mass is evaluated; it also includes flat directions.
